A balloon starts rising from the ground with an acceleration of 1.25 `m//s^(2)` . A stone is released from the balloon after 10s. Determine
(1) maximum height of ston from ground
(2) time taken by stone to reach the ground

Explanation

To solve the problem step by step, we will break down the two parts of the question: finding the maximum height of the stone from the ground and the time taken by the stone to reach the ground.

### Part 1: Maximum Height of the Stone from the Ground

1. **Determine the velocity of the balloon at the moment the stone is released**:
- The balloon starts from rest and rises with an acceleration \( a = 1.25 \, m/s^2 \).
- The time \( t = 10 \, s \).
- Using the formula for velocity:
...
